Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during electrical work.

2. Fuel System Inspection

Sub-step 1: Remove the fuel pressure gauge from the fuel rail and connect it according to the manufacturer’s specifications.
Sub-step 2: Turn the ignition key to the "On" position without starting the engine and check the fuel pressure. It should be within the range specified in the owner's manual.
Sub-step 3: If the fuel pressure is low, inspect and replace the fuel filter and check the fuel pump relay and fuse.

3. Air Intake and Throttle System

Sub-step 1: Inspect the air filter for clogs and replace it if necessary.
Sub-step 2: Check the intake manifold for vacuum leaks and repair any leaks found.
Sub-step 3: Clean the throttle body with throttle body cleaner to remove carbon deposits.

4. Ignition System Repair

Sub-step 1: Remove spark plugs and inspect for wear or fouling. Replace if necessary.
Sub-step 2: Test ignition coils for proper resistance using a multimeter and replace any faulty coils.

5. Reassembly and Final Checks

Reconnect all components, ensuring all connections are secure.
Reconnect the battery once the repairs are complete.
